I'm in the process of writing a chapter for my novel, and one of the characters happens to be Russian, but I'm not quite sure how he should be addressed. Did the Russians still refer to men as 'comrade' or do they use something different? I've typed in the Russian equivalent of 'mister', and I found 'Gospodin' via Wikipedia. As for Comrade, I'm not sure if I'm even using that word correctly - it sounds very political, and my (very minor) character is an inventor.
Can anyone be so kind as to help me out?
